Abstract

Fat hypertrophy is a less commonly known complication of autologous fat transfer. We present a 32-year-old female with left hemifacial atrophy associated with systemic sclerosis, who was treated with 7 fat transfer procedures to correct the facial asymmetry. A total of 236.5 mL of fat was injected to the hemiface over a 4-year period to achieve good symmetry. A progressively enlarging, painless, soft mass over the left parotid region was noted at 3 months after the final fat transfer procedure. Magnetic resonance imaging showed a markedly enlarged bulk of subcutaneous fat over the left cheek with no evidence of necrosis, edema, or pathologic enhancement. Concurrent weight gain was noted secondary to additional nutritional input. The patient's aesthetic, symptomatic, and functional concerns led to the subsequent removal of 115 mL fat by liposuction. LEVEL OF EVIDENCE: 5:
